Interactive Plots
Province_State - The name of the State within the USA. Country_Region - The name of the Country (US). Last_Update - The most recent date the file was pushed. Lat - Latitude. Long_ - Longitude. Confirmed - Aggregated confirmed case count for the state. Deaths - Aggregated Death case count for the state. Recovered - Aggregated Recovered case count for the state. Active - Aggregated confirmed cases that have not been resolved (Active = Confirmed - Recovered - Deaths). FIPS - Federal Information Processing Standards code that uniquely identifies counties within the USA. Incident_Rate - confirmed cases per 100,000 persons. People_Tested - Total number of people who have been tested. People_Hospitalized - Total number of people hospitalized. Mortality_Rate - Number recorded deaths * 100/ Number confirmed cases. UID - Unique Identifier for each row entry. ISO3 - Officialy assigned country code identifiers. Testing_Rate - Total number of people tested per 100,000 persons. Hospitalization_Rate - Total number of people hospitalized * 100/ Number of confirmed cases.
